    Bummers. You've already changed everything. I had an unexplainable problem just like this. The only think I could think of was a bad timing belt. Finally some guys from a country church came by and asked if they could haul the car away for me. So I let them have it. I hope you can do better than that with all the money and effort you've put in.

    Why would someone tell you their sob story without a solution added to it what a waste of time to come look and see that nothing of value was given for a fix or solution

97 oldsmobile achieva wont fire changed coil pack spark plugs cam sensor still wont start


Make sure battery has a full charge and battery connections all good.
If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
If you having a problem with more than one system, I want to check for rpm signal, that usually comes from the crank sensor. Not sure why you replaced cam sensor? I always want to check sensor wiring circuits before replacing anything. Don't replace anything unless your testing points in that direction.

I haved a 1989 Buick Park Avenue 3.8 engine...I have replaced the starter, coil pack, ignition module, crank sensor and cam sensor and still cannot get it to fire...I really NEED this car to run so PLEASE...


ok ! did you mean its got spark but does not start. if spark but does not start. check to see if its getting fuel to engine. remove air hose from throttle body and spray some starting fluid in throttle body, open throttle plate and spray some in. if car starts then stops, its a fuel problem. if no spark check the harmonic balancer on engine to see if its loose, the 3.8 engine have a crank position sensor that runs off the balancer. the rubber starts wearing out and the balancer start flopping around. and the timing gets massed up. good-day ! type in on pc browser ignition switch symtoms, and a list of things will come up. for a ignition switch controls over 50% of voltage for vehicle. good-day !

I have a 94 Buick park ave. I replaced icm, ecm, tps, map sensor, cam position sensor, and crank position sensor. Starter tested good but not getting a spark. What can it be


Have you tried testing the ignition coil pack(s)? If this goes out then there wouldnt be any spark delivered to the plugs, this part is relatively cheap and is a common problem causing no spark.

When i drive it jerks and it wasnt starting for a while one day it wouldnt start after i had been driving for a while i poured water on the coil pack and it started


I first would guess a faulty crankshaft position sensor and then ignition coil/ignition module
The problem is with the spark itself. The spark to plugs and wires are controlled by coil pack, which is attached to ignition coil, which then is connected to crank sensor. You can test crank sensor with an ohmmeter to see if it is good. I would also test each coil pack.

ECM would be the next part. Check the number on it . If it has the number 1228253 replace it anyway because they give a cutting off problem. Clean battery cables all three and replace bolts too.
